May I ask a final quick question? When one buys a mobile phone, one is told that for proper battery health the phone battery should be allowed to drain to empty and then recharged. I do not think anyone does that, however. If I see that my phone battery is at 60%, I plug it in. I think everyone has that habit. Is it the same in the case of electric cars? Do people who have 50% of battery juice in their car but are planning a long journey plug it in every time? Has anyone considered the fact that battery efficiency goes in a downward trajectory because the battery is being overcharged and the battery cycle is not being allowed to complete?
